  Abstract:In order to meet the needs of high speed and high quality spinning，the factors affecting the carding effect of MCC are analyzed，and a new composite coating MCC rack with high hardness，low Ra value of surface roughness，long service life，high corrosion resistance and maintenance-free is developed by optimizing the material，rack tooth profile，the geometry of tooth tip，tapered teeth treatment and composite coating treatment of MCC.Taking OE T 28.1 tex yarn，CJ 14.6 tex yarn and R 11.8 tex yarn as examples，the yarn quality and wear of common and new composite coating MCC are compared and analyzed.It is pointed out that the hardness of the new composite coating MCC rack is increased by 20%～30% compared with the common rack，the surface roughness Ra is 0.06 μm，the tooth width is reduced by about 60% compared with common MCC rack，and it has the advantages of good wear resistance，high clearance rate of cotton knots，low growth rate of short fibers，long service life and wide range of suitable spinning.
Key Words:MCC；rack；tapered teeth treatment；composite coating；wear resistance；service life；dyed polyester；medium cotton
